Following in Matt's footsteps, Jon Hamm made his way to Fenway Park and braved the cold to root on his favorite team in the World Series, but the two seksi actors found themselves on opposite sides!

The Mad Men actor and his actress lady friend Jennifer Westfeldt entered enemy territory to cheer on his hometown St. Louis Cardinals in a sea of Boston Red Sox fans!

We wonder what Matty has to say about all of this!

Unfortunately, Jon probably wasn't able to do too much cheering after he recently had surgery on his throat, but the fact that he was healthy enough to make it to the game is probably a pretty good sign!

However, it looks like our dreams of seeing Don Draper sing Take Me Out To The Ball Game have been dashed! LOLz!
